The surface acoustic wave properties of PbTiO/sub 3/ ceramics are improved. The ceramic systems investigated are (Pb,Ln)(Ti,Mn,In)O/sub 3/(Ln = La,Nd). The temperature coefficients of delay time are lowered to 46 x 10/sup -6// /sup 0/C, when Ln is La. A zero temperature coefficient of delay can be achieved when Ln is Nd. The Nd and In substitution also cause the electromechanical coupling factor to increase and the dielectric constant to decrease.
